Just pointing out that instead of typing 1.5mm^2 or 1.5(sq)mm you can type ²
by holding down the Alt key while typing 253 on the number pad on the right
of the keyboard like this: 1.5mm². 252 is cubed ³, 248 is degrees ° and 171
is ?. There's lots more.

Usenet was originally a 7-bit medium, and 8-bit characters won't display
in software that expects text to be basic ASCII. There isn't a single
standard for an extension to the basic ASCII set anyway, so even if
software is 8-bit capable it won't necessarily display the character
that the author intended.
